Interestingly, MAGA did in fact divide the US more than any other political movement. And the right is generally not very big on unity. Most of their "politics" today is based on oppressing and marginalizing the "other" (currently mostly LGBTQ people). The left was traditionally the movement of communities and associations. Unions, solidarity, social security. It's in their names, socialists and communists.
Individualism is a right-wing idea. And the current state of the States is reflected in the Overton window, which is far right.
What divided the country was not the MAGA movement, but the Russian Collusion Coup and fake news extrapolation, from that which started the division. If you were gullible to work under the premises of that collusion lie; for over two years I might add, then you could justify blaming everything wrong on MAGA. However, there was nothing radical about trying to recreate a time when America was unified as the defender of the free world; WWII era. Before Trump, the Left had previously divided people with the idea of diversity, not unity; Democrat Party segregation scam. If a child can learn his native tongue and not English his future options are limited to a pocket in a city or two. One common language allows him to go anywhere.
But since the lie of Trump, plotting with Putin, was swallowed hock line and sinker, that foundation premise made things appear upside down, with the true radical and divisive people continuing to lie in plain sight. Since nothing happened to the criminals who ran the coup and who even persecuted innocent people; create special affects, it was easy for the gullible to extrapolate that lie. Parents were considered domestic terrorists, by the Left, for not allowing their children to be mutilated, while criminals are now free without bail, running Democrats run cities. This all makes honest people feel alone; patients running the Lefty Asylum with the help of Big Brother.
Now House Investigations have proof that the Biden Family is among the worse exampled of corruption in US history; influence peddling for money. Thier proof has to do with banks records of questionable movement of money that all banks are required to monitor by law. It was designed for the drug traffic trade. It turns out that the Biden family had a dozen or so, LLC shell companies, that did nothing but a money shuffle ending up in th pockets of Biden family members. Biden was the one taking money from Russia; collusion, as well as China, Ukraine, Romania and any other country he was involved with as Senator and VP under Obama. All Biden and others did was project this corruption onto Trump, and the Left would eat it up with the help o fake news. When you have half the population pushing a lie, fake news cheer leading, and government resources; FBI and DOJ, adding to the fodder with CNN search and seizure exclusives, the Lefty lie spread, and now all people feel divided, either isolated in fear or unconscious guilt.They are still victimizing Trump, since they know if he was to win, the crooks will see justice.
The Durham investigation just ended and his report has been released. It does not specifically criminalize anyone, but rather shows a pattern of how top members of various intel organizations; FBI, CIA and Justice Departments, willingly ignored the truth and selectively politicizes lies. They had both data sets, since the beginning of the Collusion Coup, but they favored what would hurt Trump. Either we have the stupidest people in high places or the most corrupt. Recommendations are more about fixing this, but stop short of dealing with those, who benefitted by the corruption.
There were 51 former top level intel people, who singed off on the Hunter Biden Laptop being Russian Disinformation, just before the 2020 election. They all knew better; had all the information, but chose the lie for election interference. Durham has to deal with the existing corrupted justice department; the AG and the FBI are protecting Biden. Durham had to stop short of rubbing the corrupt bear the wrong way. But at the same time, not appearing too soft on crime, for the Republicans. He pointed out the patterns but stop short of naming names since this is easy to infer. This continue corruption and protecting it is dividing America, since the left can only lie more to protect their original lies, since the truth is not the friend of the lie.
